White Rhino is an indica-dominant feminized hybrid, 80% indica and 20% sativa, with an earthy, musky scent and hints of hashish. Green House Seeds bred it in Amsterdam from its White Widow and a selected Afghan indica, and calls it one of its old-school strains. It is a medium-sized plant that grows wider rather than taller, and it flowers in about 8 to 9 weeks indoors. Green House puts its THC at about 20%, and Leafly’s strain data puts it at about 21%.

History & lineage

White Rhino belongs to what Green House Seeds calls its White Family, the strains built on its White Widow. Green House describes it as a breeding project between its own White Widow, itself a Brazilian × South Indian cross, and a selected Afghan indica. Leafly names the second parent as a North American indica and says the strain is said to descend from cultivars from Afghanistan, Brazil and India.

The family has a Cup record. White Widow, one of its parents, won the 1995 High Times Cannabis Cup (Green House’s entry). A year later White Rhino placed second in the Bio Cup at the 1996 High Times Cannabis Cup, again as Green House’s entry. The line has carried on, too: Sweet Seeds used White Rhino as one of the three parents of Cream Caramel, alongside Blue Black and Maple Leaf Indica.

Aroma & flavour

Green House describes the scent as earthy and musky, with some notes reminiscent of hashish, and the taste as sweet and fruity. For White Rhino as a strain, Leafly users most often report earthy, woody and pungent flavours, followed by sweet and skunk. Green House names myrcene, alpha-pinene and beta-caryophyllene as its most expressed terpenes, and Leafly’s lab data also leads with myrcene, then pinene and terpinolene. Our terpene guide covers what each of those compounds adds to a smell.

Effects, as users report them

Most reportedRelaxed · Happy · Euphoric · Sleepy · Uplifted
Downsides reportedDry mouth · Dry eyes · Dizzy · Paranoid · Headache

These are Leafly users’ reports for White Rhino as a strain, most common first. Green House itself describes an intense, long-lasting stoned effect, and says White Rhino is less strong than White Widow and more relaxing. Dry mouth and dry eyes are the downsides users mention most; smaller numbers report dizziness, paranoia or a headache. How it feels depends on the person and the dose, so if you are new to cannabis, start with a small amount.

Growing White Rhino

White Rhino is a feminized photoperiod plant, so it stays in vegetative growth until the light drops to 12 hours a day indoors, or until the days shorten outdoors. Expect about 8 to 9 weeks of flowering indoors, and outdoors in the Northern Hemisphere Green House says it is generally ready in the first week of October. Our seed-to-harvest timeline shows how those weeks fit a whole grow.

Green House describes a medium-sized plant with short internodes that prefers to grow wider rather than taller; as a rough guide, plants run about 80–180 cm (2.6–5.9 ft). Green House calls it very good for sea of green and screen of green setups; our guide to SCROG explains how a screen spreads a wide plant into an even canopy. Leafly rates it a moderate grow. Green House gives indoor yields of about 550–900 g/m² (about 1.8–2.9 oz/ft²) and outdoor plants about 750–1,200 g (about 26–42 oz) each. It files White Rhino under its tropical-and-Mediterranean and moderate-and-continental climate zones. Dense buds hold moisture, so keep the air moving in late flower, and judge when to harvest by the trichomes rather than the calendar.

Is White Rhino right for you?

A good fit if
  • you want an indica-dominant strain with an earthy, musky, hash-leaning character
  • you grow in a tent or under a screen — Green House rates it very good for sea of green and SCROG
  • you want a White Widow descendant with a Cup placing of its own
Maybe not if
  • you want an energetic, daytime-style strain — energetic is one of the least reported effects for White Rhino
  • your outdoor season ends before October — an autoflower may suit you better
  • you want the simplest first grow — Leafly rates it moderate; see our beginner autoflowers

Questions buyers ask

Who bred White Rhino?

Green House Seeds bred White Rhino in Amsterdam, from its own White Widow and a selected Afghan indica. Green House’s entry placed second in the Bio Cup at the 1996 High Times Cannabis Cup.

Is White Rhino related to White Widow?

Yes. White Widow is one of its two parents; the other is an Afghan indica, which Leafly lists as a North American indica. That makes White Rhino more indica-leaning, at 80% indica and 20% sativa. We also stock White Widow seeds.

Are these White Rhino seeds feminized?

Yes. They are feminized photoperiod seeds, bred so the plants grow as females, the ones that produce buds. First time sprouting seeds? Our germination guide walks through it.

How long does White Rhino take to flower?

About 8 to 9 weeks once the light drops to 12 hours a day. Outdoors in the Northern Hemisphere, Green House says it is generally ready in the first week of October.

Heavy and Reliable

19 August 2025

White Rhino grew stocky and strong, just like you’d expect from an indica-dominant strain. The buds were frosty, sticky, and carried a sharp earthy-pine smell. The smoke is heavy, relaxing, and long-lasting—total body melt with a calm, clear mind. Perfect nighttime strain.
